For every new Smash Bros. game, there is a new leak. Just a few months after a leaker at Nintendo revealed the full roster for Super Smash Bros. 3DS, today we've got Amazon leaking new features in the Wii U version of Nintendo's colorful fighting game.

Super Smash Bros. Wii U, which will be out on November 21, won't just have new stages—it'll have a stage creation mode, according to Amazon:

Whether you're creating stages on the GamePad, competing in challenges crafted by Master Hand and Crazy Hand, or outwitting your opponents in a brand new board game mode, there's no doubt that the ultimate Smash Bros. game has arrived.

Stage creation! Board game mode! This all sounds very cool, and no doubt Nintendo was hoping to reveal it in a flashy Nintendo Direct that actually shows what those things are. Amazon has ruined everything. Guess they really don't like Nintendo.

(That Master Hand/Crazy Hand challenge thing was also teased by Sakurai a couple of days ago.)

Just one month until we get to see what this Super Smash Bros. Mario Party is all about.
